In case if on effort to start server it stops right away and log entries as below appear:
2017-06-09 15:12:06.945 704 ERROR: Can't save guid. Run once as administrator.
These logs show that hypervisor can not generate some identifiers required for server to calculate guid automatically.
There's a way to work this situation around manually:
- Go to https://guidgenerator.com/ and generate one guid with "braces" and "hyphens" options enabled
- Copy appeared line to the clipboard
- Open registry editor and go to
HKEY_LOCAL_MACHINE\SOFTWARE\Network Optix\Network Optix Media Server
- Find attribute
serverGuid, double-click it to enter edit mode and paste guid value from the clipboard
- Start the server
In case of Ubuntu-based VM server you need to modify serverGuid value which is kept in configuration file:
Open it with your favorite text editor with sudo privileges and replace zero value to the new generated one.
